[specific embodiment]
Elaborate below in conjunction with the specific embodiment of accompanying drawing to liquid crystal bubbler provided by the invention, liquid-jet device and liquid crystal liquid discharging method.
For purpose of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly, and cooperate specification appended graphic, be described in detail.Specification of the present invention provides different embodiment that the technical characterictic of the different embodiments of the present invention is described.Wherein, the configuration of each assembly among the embodiment is the content that discloses for clearly demonstrating the present invention, is not to limit the present invention.And the part of reference numerals repeats among the different embodiment, is for the purpose of simplifying the description, is not the relevance that means between the different embodiment.
Shown in Figure 2 is the structural representation of the described liquid crystal bubbler of this specific embodiment.
With reference to figure 2, liquid crystal bubbler 12 comprises a liquid crystal cavity volume 21, a nozzle 22 and an electricity resonator 23.Electricity resonator 23 is drivers that the liquid crystal bubbler is implemented the hydrojet action.Nozzle 22 is arranged on the bottom of liquid crystal cavity volume 21, and the liquid crystal in the liquid crystal cavity volume 21 is by nozzle 22 ejections, and electricity resonator 23 is used for the spray volume of the liquid crystal of control liquid crystal cavity volume 21.Liquid crystal cavity volume 21 also should comprise a liquid crystal injecting port (not shown), is used for replenishing liquid crystal.
In this specific embodiment, electricity resonator 23 is an automatically controlled pressue device, specifically comprises a piezoelectric ceramics 231 and two electrodes 232 that are connected with piezoelectric ceramics 231 electricity and 233.The characteristics of piezoelectric ceramics are can produce deformation in by the situation of electric current, and the size of deformation degree is relevant with the size by electric current, and the degree of the larger then deformation of electric current is larger.So can utilize the electrical signal of input to be the pressurization of the liquid crystal in the liquid crystal cavity volume 21 with piezoelectric ceramics 231, with the spray volume of control liquid crystal from nozzle 22.Liquid crystal is with the ejection of the state of liquid crystal drop from nozzle 22, and obviously, the suffered pressure of liquid crystal is larger, and the volume of the liquid crystal drop of ejection is just larger from nozzle 22.
Liquid crystal close contact in piezoelectric ceramics 231 and the liquid crystal cavity volume 21.As mentioned before, piezoelectric ceramics 231 is by electric current the time, because deformation can occur in piezoelectric ceramics under different electric currents, therefore in the situation of the regular variation of electric current of passing through piezoelectric ceramics 231, piezoelectric ceramics 231 can produce regular deformation thereupon, namely produce vibrations, thereby exert pressure for the liquid crystal in the liquid crystal cavity volume 21.
In other embodiment, the piezoelectric ceramics 231 of Fig. 2 also can be other automatically controlled pressue device, for example can be a solenoid and a sheet metal.Sheet metal is arranged on an end of solenoid, and with the liquid crystal close contact.When solenoid added the electricity signal intensity outside, magnetic field on every side also can change thereupon, produces vibrations thereby drive sheet metal, and then liquid crystal is exerted pressure.
Fig. 3 is the implementation step schematic diagram of method under the described liquid crystal drop of this specific embodiment, adopts the liquid crystal liquid discharging method of above-mentioned liquid crystal bubbler should comprise the steps: step S31, the liquid crystal bubbler is placed the surface of diaphragm; Step S32 is according to the size of required liquid crystal drop, for the electricity resonator of described liquid crystal bubbler applies driving voltage; Step S33 moves described liquid crystal bubbler along the direction that is parallel to described diaphragm, thereby forms equally distributed liquid crystal at described diaphragm.
Refer step S31 places described liquid crystal bubbler on the surface of diaphragm.Relative position relation in this step between liquid crystal bubbler and the diaphragm please refer to shown in Figure 1.
Refer step S32 is according to the size of required liquid crystal drop, for the electricity resonator of liquid crystal bubbler applies driving voltage.Take piezoelectric ceramics shown in Figure 2 as the electricity resonator as example, in this step, the spouting liquid of electricity resonator load voltage value and liquid crystal is proportional example in trend.If want the size of liquid crystal drop larger, then need piezoelectric ceramics is applied larger voltage signal; If instead it is less to want to control the size of liquid crystal drop, then need to reduce the voltage that applies.Experiment shows, for adopting piezoelectric ceramics as for the liquid crystal bubbler of automatically controlled pressue device, and can be with the quality control of liquid crystal drop 6 * 10
-8About mg, far below the 0.3mg of available technology adopting nature hydrojet technology.
In this step, if need more accurately to control the spouting liquid of liquid crystal bubbler, also need further to come according to the difference of liquid crystal viscosity the load voltage value of the described electricity resonator of corresponding adjustment, thereby make described liquid crystal bubbler spray needed amount of liquid crystal.About 20～30 centipoises of the viscosity of liquid crystal (CP), the about 2～5CP of viscosity of polyimides (PI).That is to say, the viscosity of liquid crystal is higher, when utilizing piezoelectric to go to the space of deformation " piezoelectric ceramics " allow the liquid crystal ejection, because the relation that the liquid crystal viscosity is higher can cause " time-delay ", or cause discharge-amount that not enough situation is arranged, then can go according to the liquid crystal of different viscositys the corresponding voltage swing of adjusting to reach needed amount of liquid crystal.For instance, the voltage of 1V can be controlled the ejection of 1mg, but in fact only has the amount ejection of 0.8mg in this specific embodiment, therefore just can be in advance on processing procedure with the voltage of 1.2V cause can 1mg amount spray.More than only understanding for convenience of description the present invention for example, is not to be limitation of the present invention.And drop size is less, and corresponding ejection frequency should be larger, and enough tight to guarantee arranging of liquid crystal drop, spacing each other is enough near, can diffuse to form each other continuous film.
Refer step S33 along the direction mobile liquid crystal bubbler that is parallel to diaphragm, thereby forms equally distributed liquid crystal at diaphragm.
After forming liquid crystal drop, quiet to a period of time, the liquid crystal drop of membrane surface can connect into the continuous liquid crystal film of one deck under capillary effect.Because the liquid crystal drop that the liquid crystal bubbler forms in the present embodiment is small-sized, so need the diffusion time of reservation relatively short, avoided in diffusion process, producing bubble.The liquid discharging method that adopts this specific embodiment is the equal of with the mode of the film forming liquid crystal that drips, distance between adjacent two blow-off points is very little, along with the carrying out of ejection technique spread film forming immediately, need hardly to reserve especially the time of liquid crystal diffusion, so lighting machine also just be can't see the phenomenon of false bubble.
And less liquid crystal drop size can also avoid producing at membrane surface the vestige of impact damage.Adopt the liquid discharging method of this specific embodiment, blow-off point is little and diffusion is even, therefore need not control especially the time that arrives ultra-violet curing envelope frame under the liquid crystal drop, also produces with regard to being not easy the edge waviness problem.
Only be preferred embodiment of the present invention below, should be pointed out that for those skilled in the art that under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
